Answer:
Explanation:
The total volume of cement in cubic feet to be made is 54 cu ft.
A concrete mixer is in volume proportions of 1 part cement, 2 parts water, 2 parts aggregate, and 3 parts sand. This means that the ratio of the ingredients is
1 : 2 : 2 : 3
Total ratio = 1 + 2 + 2 + 3 = 8
Therefore,
Volume of cement needed would be
1/8 × 54 = 6.75 cubic feet
Volume of water needed would be
2/8 × 54 = 13.5 cubic feet
Volume of aggregate needed would be
2/8 × 54 = 13.5 cubic feet
Volume of sand needed would be
3/8 × 54 = 20.25 cubic feet
